I think there isn’t really a breaking point for me… A subscription means your tied into something which can increase and your still reliant on their cloud access. I try and avoid all subscription models because they essentially lock you into a service. I dib’t use any of the tado features, I basically use it as an app control on/off switch that i can then use home assistant to control everything based on all other data in my automation. I control the hot water, heating based on each room temp manually, uses 3rd party radiator controls, using HA to tell me when i’m home or not, and turning heating on an off when required based on various room temps. So paying for a subscription just to get access to my on off switch is pointless for me. If they restrict my apis then i think switching is the best route for me
In 2026 (and even before) that simply isn’t enough anymore. You can buy a product that (when sold) advertises full local control (forever without subscription) just to - some point later in time - take your device hostage and ask for ransom if you want to continue using “your” device locally. 
With introduction of matter (online/cloud device attestation) the platform decay (or enshittification) is now lifted to another level and not owning devices anymore probably becomes the default. 
The ownership we had and were used to might soon be a thing of the past. 
In the future we will be mostly paying “rent” (even if it is a one-time payment) and probably only get a limited time of usage for a device. 
Brave new world 
The alternative (for now) still are devices that you can control and own a 100% running your code, like esphome devices. 
No argument from me on that as a policy! The only Tado device that I have is an ancient infrared thermostat (no HomeKit support) that I only use as a remote control for my mini-split air conditioner when I’m not home. There’s actually a third-party circuit board and HA integration to hard-wire full control to my AC unit, but I only used the Tado twice in all of 2025 so I don’t want to waste the time building the interface and wouldn’t pay Tado’s extortion for something that I rarely use.
Last year, Tado started sending monthly emails about my energy usage. It was hilarious to see them trying to make themselves relevant by telling me that my AC unit achieved 100% energy efficiency while turned off all winter… 
Hi,
I installed tado-api-proxy and modified the file like specified by @balk77 but I still have the same error. Even after restarted TADO bridge and Home-Assistant. The login page popups and I’m able to login to TADO but after the timeout error is raised. I wondering if the local URL is well used. Do we have a way to check that ?
Do I understand correctly that you subscribed, but the 20,000 requests are still insufficient because of the large number of devices you have?
YES, correct.
I see the same issue. Have a paid subscribtion towards Tado and 13 TRV’s. Most days I run out of API credits around 7 am and for the next 3 hours thing’s aren’t working. I am using the Advanced Heating Control blueprint, which I guess is calling the API a lot to update the offset temperature. There’s on open PR to rewamp the Tado API integration and reduce the amount of API calls, but it seems it won’t be merged any time soon - Tado refactor to tadoasync & API changes by erwindouna · Pull Request #151933 · home-assistant/core · GitHub
I have only 6 tado TRV’s and a subscription, but run into API limits every day. I’m looking to switch to another system as well. How do the Sonoff’s fare for you?
The Sonoff TRVZB works welll for me. be aware I was already having a stable and well functioning Zigbee setup (zigbee2mqtt). Not sure about the battery life, I’m only one month in…
Be aware im not using any of the advanced build in features, like scheduling etc.
I’m using set target temperature and mode, and control the target temp from HA
And using external temperatur sensors, setting the value using an automation in HA. Super simple, using some cheap Zigbee temp sensor.
